    Will be using the Gemini Restore A Deck kit to prep new wood decking. There is a concrete patio underneath the deck. Do I need to protect the concrete from the cleaner/brightening agent? If so, could you recommend the best type of material for this?

      TWP Stains · 10/16/2019
      No need to protect the concrete. Just rinse well with water when done.

    Can I wait a day between the clean step and the brighten step?

    We just recently finished installed a new western red cedar fence. The fence was completed about a month ago. Is it really necessary to wait 4 months to stain? Won't weathering the boards diminish the coloration after staining? I really love the bright orangey-red hue that the boards had right after install. I would hate to lose the natural luster of the wood by waiting so long... Also, the weather is changing quickly, so we won't be able to stay again for a long long time if we wait. Probably not until next spring.

    I'm staining a dock on tidal salt water in southeast Florida. Should I use the 100 series or the 1500 series. The dock is 3 years old and has taken a beating from the hot sun. The dock is about 450 sq. ft. How much stain will I need?

      About 5-gallons for the two coats. Use the 100 Series.

    I have 3000 sq ft of new red cedar fencing that is kiln dried. First, do I have to wait to stain it and secondly, do I have to use the restore s deck cleaner first? Or is the cleaner just for a new deck?

    I had used step 1 and step 2 in preparation for applying the 1500 product but it did not remove all of the old stain. Therefore, I sanded the deck again to make it more uniform. Do I need to retreat with Step 1 and Step 2 before applying the stain to my mahogany deck?

    Can this product be used to remove TWP 1500 series Cedartone and TWP 100 series Cedartone Natural from our cedar shingles on our house so that we may apply a lighter stain such as the 100 series Honeytone?

    I have a deck that I treated with TWP 1501 Cedartone 6 years ago. The deck is now in need of treatment because rain will no longer bead up on it. I do plan to use the Restore a Deck both cleaner and brightener. My other questions are:
    1) do I have to power wash, or can I just apply the cleaner with a 5 gallon hand pump sprayer, then rinse with a garden hose? Then repeat with brightener in hand pump sprayer, and rinse with hose?
    2) I have a lot of leftover TWP from 6 years ago. The can was opened, but has now remained sealed and in the basement (climate controlled) can I use this old can?
    3) a black mold problem. only a patch about 2 feet by 3 feet where it stays shaded almost all the time. Can I treat this with bleach, (before using the Restore a deck cleaner) and would the use of bleach in just one area make it look different from the rest of the deck?
    Thank you in advance for your help.

      1. Pressure wash while using the kit.
      2. Most likely it has gone bad if it was opened.
      3. No need to use the bleach. Use the prep kit and it will come off.

    I have read that the Gemini cleaner needs to be used within 6 hrs of mixing. Is this true? Also, does this also apply to the Brightener?
    • We will reply to your comment shortly
      TWP Stains · 09/01/2019
      Yes on the Cleaner. The brightener does not have an active shelf life so it does not matter if you use right away or a week later.

    I have a cedar deck that is many years old and I have just replaced several boards with new cedar. The remaining old boards had previously been stained with an oil based stain that has mainly worn off. The entire deck now needs to be restained. What is the best way to approach staining the combination of new and old cedar?

    I just had a new deck built in late May 2019. I want to stain the first of September. Do I need the deck cleaner or can I use the TWP 100 stain directly (Pecan color) on the new deck? My Deck is 20x40 with 8 Steps, roughly how much stain will I need to purchase? Thanks

    I had my deck previously stained with TWP stain 3yrs ago. Is it necessary to power wash all old stain off or just clean the surface before re-staining with the 100 series

      Use the Gemini Restore Kit while pressure washing for the proper prep.

    Referencing your answers to my posts on 8/11/19 concerning R-A-D Cleaner/Brightener Kit process run-off, the stain I have been using for over 15 years is Olympic Maximum #716 Semi-Transparent Cedar Naturaltone water-based stain (soap and water clean-up). After annual re-staining of the vertical deck portions for all these years, you can barely distinguish any wood grain and the color resembles a semi-gloss brown. It was re-stained July 10, 2019 and the wood and stain is in excellent condition. I want to keep this color on the vertical portions of the deck. The horizontal deck portions mentioned in the 8/11/19 post were replaced with new pressure treated pine on July 19, 2019.
    With this additional information, can you better determine if the R-A-D process runoff from the horizontal deck surfaces will affect these portions will affect this existing stain?

    I will be using the Restore-A-Deck Kit to prep the new wood on my deck and staining the new wood with TWP 1515 Honeytone stain. These newly replaced pressure treated pine rail tops, steps, bench and main deck floor have vertical parts of the deck (rail posts, fascia boards, support structure) below them that have darkened from several years of coating with a semi-transparent natural cedar color. I want those vertical parts to remain that color (essentially having a 2-tone deck).
    Will the run-off from the R-A-D cleaner and brightener processes affect the existing stain on these dark vertical parts of the deck? If so, what do you recommend to prevent this from occurring? I will be rinsing these vertical parts off thoroughly when each step is completed.

      The runoff could have some effect on the current stain as this product is designed to clean but it would depend on the stain brand and current condition of the stain. There would not be a way to prevent this if it happens.

    I will be staining new pressure treated pine on the horizontal surfaces (rail tops, steps, built-in bench and main deck floor) with TWP 1515 Honeytone stain.
    The Restore-A-Deck Restoration Kit cleaner instructions say to leave cleaner on deck surface for 15 minutes before rinsing. The R-A-D brightener says to apply brightener to entire surface but does not say for how long to wait before rinsing. Would this also be 15 minutes to wait before rinsing?

    Can I clean and brighten on the same day? Deck is a year old, pressure treated pine. First time staining this deck.

      TWP Stains · 08/08/2019
      No, TWP cannot be stained the same day as the prep. Must wait 48 hours after to prep for the wood to dry.

    Hi, we have a rough cut redwood fence that was newly installed about a year ago, just before we bought our house. It doesn't appear to have been sealed in any way, and is almost completely the new bright wood color. We're going to stain with 1501 Cedartone, but since we don't really have any effects of aging to wash away, do we need to prep with the cleaner and brightener? Would a mild soap, do get environmental dirt and dust off do the trick this time around? Thanks!

      Use the Kit for the proper prep. Thanks

    We have a cedar front porch that we are planning to clean and stain. How does one clean the cedar ceiling? It seems like the product will drip down on our heads and everywhere?

      Yes, it is hard to prep and stain a ceiling. Good news is that the Gemini Restore kit is eco-friendly and will not harm you.

    Hello! We are in central Michigan and had a new 300sf cedar KDAT deck built. We are planning on using the Gemini cleaner/brightener and then a TWP stain we like based on samples on scraps (a semi: Honey, Cedar or Pecan), once the moisture gets below 15%. Question is: sunscreen from a low-on-aerosol can got sprayed/dripped on several thirsty boards and gentle scrubbing with Dawn and warm water didn't do the trick. Will the Gemini take out the oil stains or should we just have the boards replaced? Try the cleaner and stain and then replace? Thanks in advance!

    I have a pressure treated deck with 2-3 coats of behr natural stain covering it. What should I use to remove the old stain before putting down TWP 100.
